AD293 cell line人5型腺病毒转染人胚肾细胞株

AD293 cell line
Cat No.: NTCC690213

The 293 Cell Line is a permanent line established from primary embryonic human kidney transformed
with human adenovirus type 5 DNA. The genes encoded by the E1 region of adenovirus (E1a and E1b)
are expressed in these cells and participate in transactivation of viral promoters, allowing these cells to
produce high levels of protein. E1 also complements the E1-deletion in recombinant adenoviral vectors,
allowing viral replication.
BioVector's AD293 is derived from the parental 293 cell line, but specifically selected for adenovirus applications. It
offers several advantages over the regular 293 cells:
• Flattened morphology
• Firm attachment to culture plate, ideal for amplification and tittering of adenovirus
• Larger cell surface area resulting higher transfection and better yield of recombinant adenovirus.
Medium
1. Culture Medium: D-MEM (high glucose), 10% fetal bovine serum (FBS), 0.1 mM MEM NonEssential
Amino Acids (NEAA), 2 mM L-glutamine, 1% Pen-Strep (optional)
2. Freeze Medium: 90% complete medium, 10% DMSO
I. Establishing BioVector's AD293 Cultures from Frozen Cells

Methods
1. Place 10 mL of complete DMEM growth medium in a 50-mL conical tube. Thaw the frozen
cryovial of cells within 1–2 minutes by gentle agitation in a 37°C water bath. Decontaminate the
cryovial by wiping the surface of the vial with 70% (v/v) ethanol.
2. Transfer the thawed cell suspension to the conical tube containing 10 ml of growth medium.
3. Collect the cells by centrifugation at 1000 rpm for 5 minutes at room temperature. Remove the
growth medium by aspiration.
4. Resuspend the cells in the conical tube in 15 mL of fresh growth medium by gently pipetting up
and down.
5. Transfer the 15 mL of cell suspension to a T-75 tissue culture flask. Place the cells in a 37°C
incubator at 5% CO2.
6. Monitor cell density daily. Cells should be passaged when the culture reaches 95% confluence.
